Recorded OEM specifications for the 2021 BMW i3, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.

These are vehicle-year records whose recorded OEM ranges overlap this 2021 BMW i3. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 60 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Approximate position vs the mid OEM package: outer change 1.83 mm, inner change -8.18 mm. This uses aggregated width/offset ranges, not a specific wheel.

Dataset suggestionHub-centric rings ≈ 66.7 → 66.6 mm – not a verified installation requirement.
Hub-centric rings of about 66.7 → 66.6 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore. Approximate position vs the mid OEM package: outer change -8.18 mm, inner change 1.83 mm. This uses aggregated width/offset ranges, not a specific wheel.

Donor width/offset sits outside the known OEM envelope for this vehicle. Precomputed data suggested a spacer; geometry was re-checked against OEM envelope.

Keep the BMW i3 (2021) wheel and tire close to OEM specs. The car uses 19x5.0 wheels, 5x112 lugs, 66.6mm center bore, M14x1.25 threads, ET43 offset and 155/70R19 tires. Use the on-page calculator to check alternate sizes. Confirm any missing or trim-specific values with OEM sources before buying.
Follow these steps in order. They reflect the lifecycle from planning to road verification.
If you plan a non-OEM wheel width or offset, model it first. The calculator shows wheel and tire diameter differences instantly.
Changing wheel or tire size affects handling, ride and dash instruments. Small offset shifts change scrub radius and steering feel. Wider rims or taller tires can contact suspension or bodywork. Diameter changes affect speedometer and gearing. Proper hub fit and lug seat type control vibration and safety. Using OEM-equivalent dimensions preserves factory performance and systems integration.

Be aware of common gotchas and safety risks.
If any trim-specific values are unknown, confirm them with the owner’s manual, the door placard, or a BMW dealer. Use the on-page calculator to compare designs before purchase.

Next steps: run the on-page calculator now. Then confirm any missing OEM values with official sources. Proceed to purchase and install with the checklist in hand.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
